kaisadadi Posted June 29, 2013 Report Share Posted June 29, 2013 1N后的变化太多了！有各种用法和约定，每种用法都有适合的特殊牌型。说白了，就是一种约定，赋予某种叫品，某种含义。体系怎么套用比较合理，出现的频率高不高，需要选择。 Quote Link to comment Share on other sites More sharing options...

kaisadadi Posted June 30, 2013 Report Share Posted June 30, 2013 3C正确防守，-13C能否成为最终定约呢？北家4441，如果选择X，南叫出3H也没什么难度。 Quote Link to comment Share on other sites More sharing options...
kaisadadi Posted June 30, 2013 Report Share Posted June 30, 2013 南家该pass，整手牌控制太差除D以外，三门花色没控制，尤其SQ*缺少保护张，该示弱 Quote Link to comment Share on other sites More sharing options...
xuefeier Posted June 30, 2013 Report Share Posted June 30, 2013 另外除S外，将牌质量差 Quote Link to comment Share on other sites More sharing options...
lycier Posted June 30, 2013 Author Report Share Posted June 30, 2013 1-牌力分散2-被过高估值的Q太多了3-主要牌力集中偏赘在边花♣上 Quote Link to comment Share on other sites More sharing options...
yunling Posted June 30, 2013 Report Share Posted June 30, 2013 北家应该PASS 1NT，8点均型没有必要在1NT后行动。 Quote Link to comment Share on other sites More sharing options...
madongjun Posted July 1, 2013 Report Share Posted July 1, 2013 用了这个约定叫，必然得有其他约定叫或者自然叫牌被迫让步，所以约定叫在一套体系中要系统的用才不会发生冲突。 Quote Link to comment Share on other sites More sharing options...
madongjun Posted July 1, 2013 Report Share Posted July 1, 2013 没有中间张支持有Q必须减值，所以开叫不叫1NT也许后续才能把握好。 Quote Link to comment Share on other sites More sharing options...
madongjun Posted July 1, 2013 Report Share Posted July 1, 2013 南北家都是边缘牌力，碍于局况不利，才失去争取部分定约的机会，殊为可惜！ Quote Link to comment Share on other sites More sharing options...
yunling Posted July 1, 2013 Report Share Posted July 1, 2013 1NT可以MK的牌，去打3C-1 ;) Quote Link to comment Share on other sites More sharing options...
madongjun Posted July 2, 2013 Report Share Posted July 2, 2013 合并帖子后，原先的针对不同帖子的跟帖就按时间顺序重新排列了－－给我一种摸不着头脑的感觉。 Quote Link to comment Share on other sites More sharing options...
